i would definitely give this guy a bad review because knowing if it is hacked or not is a really important thing to leave out. if someone else got this and happened to them i am sure they would have reported this guy to ebay because of it being hacked. i would still report him if it ends up being totally bricked in the end

The wii is not bricked, it is completely fine. Possibly the seller did not know it was hacked? Or thought the hack was removed.

I plan on it. And if I remember correctly from my og XBOX modding days, its illegal to sell modded game consoles on eBay (in the US). Or maybe that was just because it was hard modded. But that's a huge thing to leave out on an eBay add. But he/she is definitely getting a bad review.
